Baryogenesis in the SV0 Model: Matter-Antimatter Asymmetry from Two-Sector Dynamics

This manuscript is the fourteenth paper in a series establishing the Signed-Volume Effective-Fluid (SV0) model. In Papers I-XIII, we introduced the SV0 model, derived its microphysics, analyzed its perturbations, established its dynamical stability, provided a string-theoretic embedding, constructed a unified cosmological history with an early-universe bounce, resolved the cosmological constant problem, analyzed CMB signatures, explored its quantum cosmology, and provided a discrete spacetime derivation. In this fourteenth work, we demonstrate that the SV0 model naturally incorporates all three Sakharov conditions for baryogenesis. By identifying the two SV0 sectors (V_A > 0 and V_B < 0) as the matter and antimatter sectors respectively, we show that the SV0 exchange law provides the required baryon number (B) violation. The soft symmetry-breaking term ε, introduced in the microphysical derivation (Paper II) to select the x0 > 1/2 branch, acts as the source of C and CP violation. Finally, the early-universe bounce (Paper IX) provides the necessary out-of-equilibrium dynamics. We calculate the resulting baryon-to-entropy ratio and show that the SV0 geometric parameters naturally yield the observed asymmetry η ~ 10^-10. This demonstrates that the SV0 framework is a comprehensive theory of the universe's origin, evolution, and composition.
